A method of manufacturing an article by diffusion bonding at least two metal components ( 30,36 ) comprises assembling the metal components ( 30,36 ) into a stack relative to each other so that the surfaces ( 34,40 ) are in mating contact. The edges of the metal components ( 30,36 ) are sealed together, except for an aperture ( 49 ) where a pipe ( 50 ) is to be connected. A connector ( 51 ) has a first end ( 52 ) and a second end ( 53 ). The first end ( 52 ) has a smaller diameter than the second end ( 53 ) and a bore ( 54 ) extends through the connector ( 51 ) from the first end ( 52 ) to the second end ( 53 ). The second end ( 53 ) of the connector ( 51 ) is joined ( 57 ) to the stack. The pipe ( 50 ) is joined ( 58 ) to the first end ( 52 ) of the connector ( 51 ). The interior of the sealed assembly is evacuated via the pipe ( 50 ) and the pipe is sealed. Heat and pressure are applied to diffusion bond the metal components ( 30,36 ) together to form an integral structure. The connector ( 51 ) reduces the possibility of failure of the pipe ( 50 ) and/or seal ( 57 ) during diffusion bonding.
